    Weekly "anything goes" thread!

    Posted: 27 Mar 2020 05:40 AM PDT

    Here's your chance to talk about whatever!

    Although if you're thinking about getting feedback on an app, you should wait until tomorrow's App Feedback thread.

    Remember that while you can talk about any topic, being a jerk is still not allowed.

    What stops Android apps from reaching feature parity with equivalent iOS apps?

    Posted: 26 Mar 2020 10:17 PM PDT

    For example, why is Spotify so far behind on android? There are useful features that we've been missing for years. I even saw a whole advertisement on Instagram specifically for Spotify's swipe to queue and save songs feature. (This feature is iOS only.) How can they blatantly and shamelessly neglect Android, or is there a reason? Yes I am a little salty

    I just published my first Medium article talking about how to get rid of Fragment/Activity boilerplate code (especially with MVVM). Would love some feedback!

    Create simple CPU intensive task?

    Posted: 27 Mar 2020 04:39 AM PDT

    Hello!

    I'm working on a app that has 3 buttons:

    LOW, MEDIUM, HIGH

    Those buttons corresponds to CPU intensity, what would be the easiest way to create a CPU intensive task that can generate a low, medium and high load?

    Thank you!

    [It's 2020] Does anyone still use Genymotion ?

    Posted: 27 Mar 2020 08:07 AM PDT

    I use Docker to deploy and test my web app, but Docker use Hyper-V, which would never work with Virtual Box (used by Genymotion). So i am planning to switch back to Android Studio Emulator.

    Is this a good solution ?, how about the performance of AS Emulator compared to Genymotion ? Which emulator are you using ?

    Thanks in advance

    Firebase analytics in Android library

    Posted: 27 Mar 2020 07:15 AM PDT

    I'm transitioning a part of my app into a distributed library that other apps can use. I'd like to still get analytics events though even if it's being used in someone else's app.

    Does Firebase allow analytics from a library to go to one Firebase project, and analytics from the app to go to another? Is it as simple as including the google-services.json with library?

    Handle Dynamic runtime overlays (RRO)

    Posted: 27 Mar 2020 12:05 AM PDT

    Hi! I'm using Dynamic Runtime Overlays in my AOSP image, and I have a problem with handling overlays. Each enable or disable of the overlay leads to restart of the every application but without any onConfigurationChange received. I would like to prevent some applications from restart such as map application to avoid lengthy initialization process.

    Thanks for help!

    How does token flow work in android app?

    Posted: 27 Mar 2020 12:01 AM PDT

    Is this how the token flow works?

    1. Authenticate user
    2. Get token
    3. Enter android app content
    4. On each request token is being sent in the request

    Questions:

    1. What if token is expired? Do I logout user and send him back to authentication screen?
    2. If user is already logged in, and he enters app second time, do I validate user with previously stored token?
    3. Do I use some crypto tools to obfuscate token before storing it on the device?

    Who else gets these Maven errors constantly during building in the last few weeks?

    Maven seems to be down almost every day at least once. How can I force Android Studio to not check this on every build?

    Has anyone else experienced low AdMob/MoPub/other ad company eCPM & match rates during COVID-19?

    Posted: 27 Mar 2020 05:35 AM PDT

    I apologize if this is the wrong place to ask this question. If it is, feel free to remove this post and point me in the right direction.

    I have an app in the App Store and Play Store that is seeing more users during the quarantine, but my ad rates have been absolutely terrible over the past month and a half.

    I'm using AdMob with mediation that's serving MoPub ads, and my match rates have fallen to ~70% and my eCPM is below $0.10 (for banner ads). I'm used to seeing match rates in the middle 90s% and an eCPM at around $0.20.

    Has anyone else noticed a drop-off in rates since COVID-19?

    Thanks for your time and help!

    Let's build an open source COVID-19 app

    Posted: 27 Mar 2020 04:57 AM PDT

    With the Coronavirus spreading like wildfire these days, a lot of people are helping each other. In my local community I see a lot of people helping elderly/sick people by cooking for them, warning them about regulations, running errands for them or just chatting with them from a distance because they are quarantined and have no social contact. I hope I'm not alone this, but I feel like I also need to help anyway I can. And I know can make/publish an Android app and write some reasonable code. There are/were a lot of apps spreading misinformation on this issue, hell some even put ads/premium functions on those apps. For that reason Google has blocked all COVID-19 apps.

    So why not create a comprehensive open source COVID-19 app as a community?

    Considering there is a complete lack of a good map/overview app for this on the Play Store at the moment. Maybe if we do this as a collective with only official information from the WHO/NHC, Google might consider allowing this app to be available on the Play Store.

    Some requirements:

    • Confirmation from Google (yeah..)
    • A list of contributors
    • Someone who wants to lead this thing (or maybe a few people)
    • Wireframes/Mockups
      • If you don't have a lot of experience with Android you can still contribute by creating Wireframes/mockups.

    Some things to setup:

    • A repository
    • A Slack channel (or something else)
    • Project overview (Kanban board)
    • List of requirements
    • List of things to implement (backlog)

    I haven't really seen an open source app succeed on a subreddit before, so this is probably going to fail. But let's give this a try. Leave a comment if you want to help.

    Link to the Github organisation page.

    Link to the android app repository.

    Is it acceptable to disable landscape mode in commercial apps?

    Posted: 26 Mar 2020 07:08 PM PDT

    The KFC food delivery app doesn't have landscape mode, at least the app that is used here in Malaysia. So here I am thinking, if the app's layout doesn't look good in landscape there is no need to force the matter and I can just disable it. But is this practice acceptable?

    I am making this personal app as a portfolio and I was concerned that employers might start asking me about it and then condemning my design choice during the interview.

    Neumorphism Style

    Posted: 26 Mar 2020 08:14 PM PDT

    So I've seen this neumorphism style around a lot recently and have been interested in trying to implement it.

    From what I've read, the design utilizes two shadows to achieve this look. I've searched online but couldn't find anything about adding two different shadows to a button.

    So any help in the right direction would be appreciated.

    Playstore versioning issue

    Posted: 26 Mar 2020 10:41 PM PDT

    Hi, my first release was using app bundle. Yesterday I generated3 different APK with versions 4008,2008,1008 respectively and published them.

    However, now I want to generate app bundle and the version it gives is 9.

    Does this mean I have to change my appbundle version to above 4008?

    What should I do? jumping from 9 to 4009 is a big number for app bundle

    How long till Google indexes my app?

    Posted: 26 Mar 2020 09:40 PM PDT

    Hi all,

    So after much work, my app got published to the app store yesterday (yay!) (shameless plug --> Mylist)

    I was wondering, how long does it take for Google to fully index and add my app to their search results? I'm a new to the Play Store so I'm guessing it will take some time but I'd like to know how long it took you folks to get be shown in the search results.

    Cheers!

    Google Play search rankings glitchy lately?

    Posted: 26 Mar 2020 09:23 PM PDT

    My app was #1 for particular search keywords yet has dropped very low down the list in the past 24 hours. On some devices I can't even find the app if I search for it anymore. Anyone else out there with similar experience?

    It feels like Google Play glitched and started using some old data for app rankings or something?

    Freeing up a Package Name

    Posted: 26 Mar 2020 05:03 PM PDT

    Hi All.. I was trying to figure out if removing an app from the Play Store would free up the package name (i.e. I can upload another app using that same package name).

    AR-GO: AR based interactive realtime 1v1 shooter

    Posted: 26 Mar 2020 10:07 AM PDT

    Hey Reddit,

    Around 1.5 years back, me and my friends won a hackathon where we made an augmented reality based multiplayer shooter game. I was finally able to polish it out and release it on play store.

    AR-GO is an augmented reality based interactive 1v1 realtime shooter where two players create an arena in real world and engage in shootout to eliminate the opponent.

    AR-GO needs another player around you in the same world environment. Both players place objects in the same 3D world between them. The AR world is created such as to allow players to hide behind objects. Both players can strategically place objects and the objects are synced between both the players. Players try to hit headshots or body shots while hiding behind the virtual arena. I hope people can enjoy this game while at home where they can play with their family members.

    Play store - https://play.google.com/store/apps/details?id=com.tosc.argo

    The app is paid as the underlying APIs have quotas and are expensive. The source and demo gameplay video is available on the hackathon project page -

    https://devfolio.co/submissions/player-known-battle-grounds

    The code wouldn't be of high quality as its was made in around 12 hours at a hackathon, the code for play store version is not open source and adds play games integration and lots of other changes but most of core part is there in the GitHub link. For the technical side- ARCore cloud anchors are used to sync the AR world between two players, on device ML is used to identify headshots and body shots and firebase realtime database is used for bullets and damage sync between players within 100ms.

    If you want, an apk is also available on the XDA thread - https://forum.xda-developers.com/android/apps-games/ar-ar-based-interactive-real-time-real-t4072273

    I am looking to add more game modes and gun types. Looking forward for the feedback!
